Grommet wrong assembly preventive structure

Abstract

The fit portions 10 of the right and left grommets 6 are structured such that each of the fit portions 10 extends across a portion of the wire harness covering cylindrical body 7 of the grommet 6 in the peripheral direction of the wire harness covering cylindrical body 7, the two side portions of such extending-across fit portion with the wire harness covering cylindrical body 7 as the boundary thereof are formed asymmetric in shape, and, when the right and left grommets 6 are positioned in the same direction, the fit portion 10 of the right grommet 6 b is set so as to be rotated 180 ° with respect to the fit portion 10 of the left grommet 6 a; in each of the right and left grommets 6, there is formed a display portion 12 which can be used to indicate the position and direction of the grommet 6 when assembling the same or can distinguish the assembling sides of the right and left grommets 6 from each other when assembling the same. On the other hand, the fit holes 8 of the right and left body panels 1, into which the fit portions 10 of the right and left grommets 6 are to be fitted, are disposed such that, on the right and left sides of the vehicle body, they are formed so as to be rotated 180 ° with respect to each other in correspondence to the setting of the fit portions 10 of the right and left grommets 6.

What is claimed is:  
     
       1. For use in a structure for assembling grommets of a right and left common use type comprising: 
       a plurality of wire harnesses, the outer peripheries of two wire harnesses of said plurality of wire harnesses respectively disposed so as to penetrate through at least one of their associated body panel and through their associated opening/closing panel openably and closably mounted on the right and left sides of said body panels by hinge portions, said two wire harnesses covered by wire harness covering cylindrical bodies of right and left grommets respectively formed so as to have the same shape, said right and left grommets having two end portions of said wire harness covering cylindrical bodies which are inserted through fit holes respectively formed in said body panels, wherein at least one-end sides of said wire harness covering cylindrical bodies of said right and left grommets, in fit portions respectively formed in the outer peripheries of said wire harness covering cylindrical bodies of said right and left grommets so as to be integral therewith, are fitted into their corresponding ones of said fit holes formed in said body panels;  
       a grommet wrong assembly preventive structure, each of said fit portions of said right and left grommets extending across a portion of its associated wire harness covering cylindrical body in the peripheral direction thereof, and two sides of said extending-across fit portion with said associated wire harness covering cylindrical body as the boundary thereof are formed asymmetric in shape;  
       when said right and left grommets are positioned in the same direction, said fit portion of said right grommet is set so as to be rotated 180° with respect to said fit portion of said left grommet;  
       in said right and left grommets, there are respectively formed display portions which can be used to specify the position and direction of said right and left grommets or distinguish the assembling sides of said right and left grommets from each other when assembling the same; and, said fit holes of said right and left body panels into which said fit portions of said right and left grommets are to be fitted, on the right and left sides of a vehicle body, are disposed so as to be rotated 180° with respect to each other in correspondence to said setting of said fit portions of said right and left grommets.
